When performed by an experienced orthopedic surgeon like Dr. Dheeraj Dubay — a leading joint replacement surgeon in India with 25,000+ successful surgeries — the process is smooth, safe, and highly predictable.

In this blog, we break down every stage of total knee replacement surgery, what affects the duration, and what patients can expect before, during, and after the procedure

How Long Does Knee Replacement Surgery Take? (Detailed Breakdown)

Actual Surgical Time: 60–90 Minutes

The average knee replacement surgery time typically ranges between 1 to 1.5 hours.
However, the total OT (operation theatre) duration may extend to 2–3 hours, including anesthesia, patient preparation, and post-surgical stabilization.

1. Pre-Operation Preparation (20–30 Minutes)

This includes:

• Positioning the patient

• Sterilization of the surgical site

• Administering spinal/epidural anesthesia

• Setting up instruments

This stage is handled by the anesthesia team and the supporting staff.

 2. The Actual Total Knee Replacement Surgery (60–90 Minutes)

During the main procedure, the orthopedic surgeon performs several steps:

Step-by-Step Process

1. Incision over the knee joint

2. Removal of damaged cartilage and bone

3. Alignment of bones

4. Placement of prosthetic implants

5. Verification of mobility & stability

6. Closing the incision

Advanced techniques like robotic knee replacement or computer navigation may slightly increase preparation time but offer higher accuracy and faster recovery.

 3. Immediate Post-Surgery Care (30–45 Minutes)

Once the total knee replacement is complete:

• The patient is shifted to a recovery room

• Vitals are monitored

• Pain control medications are administered

• Initial movement assessment is done

This phase ensures the patient is stable before being moved to their room.

Factors That Affect Knee Replacement Surgery Time

1. Technique Used

• Traditional TKR → 60–75 minutes

• Navigation-assisted TKR → 70–90 minutes

• Severe arthritis

• Previous fracture

• Revision surgeries
  All may extend surgical time.

3. Patient’s Health Condition
